Selina Concise Physics Class 10 ICSE Solutions Refraction of Light at Plane Surfaces Selina ICSE Solutions for Class 10 Physics Chapter 4 Refraction of Light at Plane Surfaces Exercise 4(A) 1. What do you understand by refraction of light? Solution 1. The change in the direction of the path of light, when it passes from one transparent medium to another transparent medium, is called refraction of light . 2.Draw diagrams to show the refraction of light from (i) air to glass, (ii) glass to air. In each diagram, label the incident ray, refracted ray, the angle of incidence (i) and the angle of refraction (r). Solution 2. 3. A ray of light is incident normally on a plane glass slab. What will be (i) the angle of refraction and (ii) the angle of deviation for the ray? Solution 3. The ray of light which is incident normally on a plane glass slab passes undeviated. That is such a ray suffers no bending at the surface because here the angle of inc...
